Choosing the auspicious day of the ecliptic is dominated by the fate of women and supplemented by the fate of men. In addition to the fact that the date of marriage cannot conflict with the year of both men and women, the first choice is the Italian month and the small profit month of the woman, so as to avoid the evil month that hinders menstruation, parents, husband and woman.
